Isotropic collision induced light scattering spectra from gaseous SF6

The experimental binary isotropic collision-induced light scattering spectrum of the gaseous sulfur hexafluoride is measured in absolute units in the 30–210 cm−1 frequency range. The contribution of dipole–multipole mechanisms is computed in a semi-classical way. From comparison with experiment, the independent component E of the dipole–octopole polarizability tensor is estimated. This evaluation is compared to a recent theoretical ab initio calculation.
